Worked examples¶
One ready-to-run specification per design family ships with the package. pilotr_example() lists them and returns the path to each for load_spec(), and the same JSON files drive the R package and the no-code app. Each is
simulated below, showing the design it describes and the first rows of the data it produces. The
specification format is documented on the Specification page.
